Film clips looping, rewritten with new gender roles. (some with
volume, some not, so film bursts out at random)

Bathroom doors to enter new sections (or whole thing) : one door
could lead to visual of how gender roles REALLY progress, and the other to
the brainwashing part; or just whole thing to enter, both lead to the same
part. which seems like a better point to make.

Have people doing intake forms harassiong patrons, playing gender
police - can have them decide at the door whether they want to play, wear
a tag. Or have "volunteers planted in audience" thing to scare folks.
